Yog tias koj ua haujlwm hauv kev tsim khoom lag luam, cov khoom siv hauv tsev, lossis cov khoom siv ua kom zoo, koj yuav tsum tau ua rau muaj ntau yam, koj yuav tsum tau siv cov hlau uas muaj zog thiab ua siab tawv. NkagDC01 Hlau{{0- ib qho txias {{1} {{- Txoj kev sib sau ua ke los ntawm kev sib sib zog nqus duab. Nws cov nplaim du, cov khoom siv microstration microstructure, thiab txhim khu kev ua tau zoo ua rau nws yog staple hauv kev lag luam thoob ntiaj teb. Hauv phau ntawv qhia no, peb yuav tawg DC01 tus qauv sib xyaw, cov ntawv thov ua tau zoo li cov kws tshaj lij, thiab yuav ua li cas suav nrog kev pom ntawm cov txheej txheem hlau xws li beray hlau.
DC01 steel?
DC01 steel belongs rau "DC" (captacts) tsev neeg) tsev neeg ntawm cov hlau, qhov twg cov tsiaj ntawv "01" txhais tau nws cov xwm txheej uas yog tusQib theem pib QibRau cov colden ntau - kev sib sau siv. Tswj hwm los ntawmEn 10130: 2006(Txias - rolled Mild steel tiaj tus khoom rau cov khoom txias los ntawm kev hla nws los ntawm cov txiv ntoo ntawm chav tsev.
Tsis zoo li siab -} Cov ntsiab lus ntawm cov ntsiab lus ntawm lub zog, ua rau nws zoo tagnrho rau cov khoom sib tsoo yam tsis muaj kev tawg. Nws cov txheej txheem huv kuj ua cov txheej txheem theem nrab zoo li txheej, pleev xim, thiab vuam {}}} Cov ntsiab lus tseem ceeb rau kev lag luam uas xav tau kev lag luam ob qho tib si. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias DC01 uas tsis muaj kev kho mob corrosion, yog li kev kho kom nto yog feem ntau tsim nyog rau kev siv ntev.
DC01 Hlau: Khoom Siv Tseem Ceeb
1. Tshuaj lom neeg sib xyaw
| Lub ntsiab | Cov ntsiab lus (Max,%) | Lub hom phiaj |
|---|---|---|
| Carbon (c) | 0.12 | Tswj lub hardness; Qib qis ua kom muaj kev ductility siab rau kev sib tsoo txias. |
| Manganese (mn) | 0.60 | Boosts lub zog thiab saum npoo ua tiav yam tsis muaj kev cuam tshuam kev sib deev. |
| Phosphorus (p) | 0.045 | Me ntsis nce zog tab sis tsuas yog txwv kom tsis txhob txo cov tawv. |
| Sulphur (s) | 0.045 | Txhim kho tshuab luam ntawv; lawb tsawg kom tsis txhob poob ntawm ductility. |
| Aluminium (AL) | 0.07 | Deagidizes cov hlau, ua kom cov qauv grain rau cov khoom zoo dua qub. |
| Hlau (FE) | Seem | Lub hauv paus hlau, sib sau cov hlau lub matrix. |
2. Cov Khoom Siv Neeg Kho Tshuab
- Tos lub zog (RES): 140-280 MPa - qhov kev ntxhov siab ntawm cov hlau pib deform plastically, ua rau nws yooj yim kom muaj kev puas tsuaj tas mus li.
- Tensile lub zog (RM): 270-410 MPa - nruab nrab lub zog ua kom muaj zog tuav lawv cov qauv hauv kev siv, txawm tias tom qab sib sau ua ke.
- Elongation (A80): Ntau dua lossis sib npaug zos rau cov hlau kom ncab thaum lub sijhawm sib sib sib zog nqus lossis khoov tsis tau kua muag.
- Brinell Hardness (HB): 80-120 - Tus qauv muag uas yooj yim stamping thiab txiav.
- Elastic modulus (e): ~ 210 GPA - zoo sib xws nrog lwm cov Qis- Cov hlau me, ua kom muaj kev ntxhov siab hauv kev ntxhov siab.
3. Lub cev lub cev
- Qhov ceev faj: 7.85 g / cm³ - qauv rau cov hlau hlau, ua kom muaj kev ruaj ntseg qauv.
- Melting taw tes: ~ 1,460℃- raug rau cov hlau me me, tau tshaj nrog cov txheej txheem kev tsim khoom.
- Thermal Conductivity: 54 W / MIN - Cua sov tsis txaus, zoo tagnrho rau cov cuab yeej siv hluav taws xob tau hloov.
- Sib nqus cov khoom: Ferromagnetic - muaj txiaj ntsig rau hluav taws xob sib dhos uas xav tau sib sib sib nqus.
Cov Ntawv Qhia Tseem Ceeb ntawm DC01 Hlau
| Yam zoo | DC01 Hlau | DC03 Hlau | Tseem Ceeb Takaway |
|---|---|---|---|
| Muaj meej | Txheem (Kev Siv Dav) | Txhim kho (kev sib sib zog nqus duab) | DC03 leeg ntawm cov duab ua ke (piv txwv li, sib sib zog nqus - kev tawm tsev) zoo dua. |
| Paib lub zog | 140-280 MPa | 120-210 mpa | DC03 lub zog qis zog zog tso cai ntxiv cov khoom siv yas ntxiv. |
| Elongation | Ntau dua los yog sib npaug rau 28% | Ntau dua los yog sib npaug rau 34% | DC03 yog ntau ducile, txo cov kev pheej hmoo thaum lub sij hawm drill. |
| Nto Zoo | Zoo | Zoo heev | DC03's smoother nto yog qhov zoo rau high-}} kawg txheej txheej. |
| Cov Ntawv Thov | Nkhaus, tso zis | Automotive sab hauv vaj huam sib luag | Xaiv DC01 rau kev yooj yim; DC03 rau kev ua kom precision. |
| Tus nqi | Qi dua | Me ntsis siab dua | DC01 muaj tus nqi zoo dua rau tsis - tseem ceeb |
